African genera Desplatsia and Duboscia ; and we have made the 

 total number of distinct genera thirty-eight, in describing recently 

 the two exceptional types Solmsia 1 and Vasivaa. 2 



The latest authors who have completely studied this group, Ben- 

 tham and Hooker, 3 have divided it into seven tribes, 4 which we have 

 thought necessary to reduce to four, by uniting two and two, those 

 which are only founded upon the difference of form presented by 

 the internodes of the receptacle, in the interval which separates the 

 insertion of the corolla from that of the androceum. 5 The special 

 character of these series consequently become the following : — 



I. Brownlowie^e. — Calyx gamosepalous, campanulate, with 

 three, four or five valvate divisions. Internodes little developed 

 or wanting in the interval of the petals and the androceum. Petals 

 coloured. Anthers short, generally globular or didymous, with the 

 lines of dehiscence confluent at the summit. — (7 genera.) 



II. Tiliece. — Calyx with distinct sepals. Petals coloured, inserted 

 against the stamens or separated from their insertion by a more or 

 less elongated internode, glandular in its upper portion, and in this 

 case furnished within their base with a dimple or plate, which 

 moulds itself upon a corresponding face of the receptacle. 7 — 

 (21 genera.) 



III. Prockie.e. — Calyx with distinct sepals. Petals not at all, or 

 but little developed, sepaloid, often in the form of tongues or teeth. 

 Anthers short, subglobular or didymous, dehiscing by longitudinal 

 clefts. — (4 genera.) 



IV. ELJ^ocARPEiE. — Calyx valvate, or more rarely imbricated. 

 Petals wanting or incised, lobed. Anthers linear, dehiscing from 

 the summit for a variable distance, often inconsiderable. Andro-
